About these rates

Argentine banks set their own retail buy and sell for the dollar on top of the wholesale rate, and the spread is several percent. The Banco Central de la República Argentina publishes the wholesale reference rate. The Banco Central de la República Argentina official rate is shown next to each row.

Why use bank board rates through an API?

The Banco Central de la República Argentina official rate is what accounting, tax and customs rules name, but it is not what a customer pays at the counter or in an app. Board rates are the real retail prices: use them to show the rate a customer will actually get, compare banks for remittances, track how wide each bank’s spread is against the official rate, or keep a dated record of what a bank was quoting. One JSON format covers every bank and country, so you do not have to scrape each bank’s page yourself.

Frequently asked questions

What is the difference between a bank’s buying rate and selling rate?

Both are quoted as the local currency per one unit of the foreign currency. The buying rate is what the bank pays you when you hand it foreign currency; the selling rate is what it charges when you buy foreign currency from it. The gap between them is the bank’s spread.

Why do these rates differ from the central bank rate?

The central bank publishes one reference rate per currency per business day. Banks quote around it with a margin and refresh their boards several times a day. The central bank row is the number to use for accounting, tax and customs; the bank rows are what you would get at the counter or in the app.

How often are the bank rates updated?

AllRatesToday reads each bank’s public rates page once an hour and shows the time next to every row. Where the bank prints its own last-updated time, that is shown instead. Banks can change boards between reads, so treat every figure as indicative and confirm with the bank before a transaction.

Can I get these rates through an API?

Yes, with a free API key. The endpoint /api/v1/bank-rates/{country} returns every covered bank’s latest board as JSON, and /api/v1/bank-rates/{country}/{bank} returns one bank, optionally narrowed with ?ccy=INR. Attribution back to allratestoday.com is required.
